Leon Romanovsky d05d4ac4c9 RDMA/cm: Add SET/GET implementations to hide IBA wire format
There is no separation between RDMA-CM wire format as it is declared in
IBTA and kernel logic which implements needed support. Such situation
causes to many mistakes in conversion between big-endian (wire format)
and CPU format used by kernel. It also mixes RDMA core code with
combination of uXX and beXX variables.

The idea that all accesses to IBA definitions will go through special
GET/SET macros to ensure that no conversion mistakes are made. The
shifting and masking required to read the value is automatically deduced
using the field offset description from the tables in the IBA
specification.

This starts with the CM MADs described in IBTA release 1.3 volume 1.

To confirm that the new macros behave the same as the old accessors a
self-test is included in this patch.

Each macro replacing a straightforward struct field compile-time tests
that the new field has the same offsetof() and width as the old field.

For the fields with accessor functions a runtime test, the 'all ones'
value is placed in a dummy message and read back in several ways to
confirm that both approaches give identical results.

Later patches in this series delete the self test.

This creates a tested table of new field name, old field name(s) and some
meta information like BE coding for the functions which will be used in
the next patches.
